Contest between diverging k-vectors and astigmatism in an aberrated randomly scattered light
Abhijit Roy, Maruthi M. Brundavanam
The impact of astigmatism on randomly scattered light, here speckles which are generated from a ground glass (GG) plate, is investigated by studying the change in the shape of the…

Anomalous Lasing Behavior in a Nonlinear Plasmonic Random Laser
Renu Yadav, Sourabh Pal, Subhajit Jana +3
An unprecedented double-threshold lasing behavior has been observed in a plasmonic random laser composed of Au nanoislands decorated on vertically standing ZnO nanorods, infiltrate…
